In the old case, there was an uncontrolled T-type junction where 5 junction branches were connected at the Ünye Industry Junction. Lane discipline was not provided at the intersection. Access to the main road from the side roads and secondary roads was irregular. The traffic flow on the main road is high since the intersection is located on the ring road connection. For this reason, the uncontrolled nature of this intersection, the insufficient geometrical arrangements and the lack of lane discipline increased the risk of accidents. With the work done, traffic islands were created at the intersection and transfers were provided with free passages. By creating partial medians on the secondary roads, lane violations of vehicles are prevented. Lane discipline is provided. By creating left turn pockets and refuge pockets, the main stream traffic is prevented from slowing down with turns and turnouts. In addition, safe return and participation with pockets were ensured. Previously, there were 5 junction branches connected to the junction by side roads and secondary roads, but with the replanning of the side roads, the junction arms connecting to the junction were planned as 4. The intersection is signalized and signal phase optimization is done.
